In brief: Size and feature
Tumors > 6 CM are high risk for malignancy.
Tumors 4-6 CM are in the gray zone (you need to look at other fearues as well). Tumors < 4 CM are less likely to be malignant. There are features on the imaging studies that can also help your physcian determine the likelihood of tumor malignancy potential (hounsfield units, contrast wash out...).

In brief: Clinical picture
I agree with dr orr. A cancerous adrenal tumor looks different, and it will act differently (grows rapidly or produce excessive amounts of hormones).
If these features are present, your dr may rec eval by a surgeon for removal- a pathologist can tell you if it was cancer after looking at the surgical specimen.

In brief: Most are benign
Fortunately most adrenal tumors are benign.
Work-up for adrenal tumors includes hormone checks to see if the trumor is producing abnormal amounts of hormones, the size of the tumor (less than 4 CM is almost always ok) and radiographic characteristics. Needle biopsies of adrenal masses are rarely helpful unless they are used to rule out metastases (from lung cancer, etc.).
